PROCESS OF EMBROIDERING.

Specification of Letters Patent.

Patented Feb. 27, 1917.

Application filed March 15, 1912. Serial No. 683,953.

To all whom it may concern:

Be it known that I, RUDoLF zen of the United States, and a resident of Camden, Camden county, New Jersey, have invented an Improved Process of Embroidering, of which the following is a specification.

My invention relates to the art of embroidery or the formation of stitches in ornamental patterns or designs whether of a predetermined character or not upon the surface of a fabric, and my invention consists of an improved method or process of effecting the application of such stitches to the fabric to define the desired ornamentation or design.

My present invention, in some respects, is in the nature of an improvement upon the method or process described in my Patent No. 1,086,190, dated February 3, 1914. In other respects, however, my present invention differs radically from the method or process of my pending application. In carrying out the process therein described in which a single oscillating needle is employed to form the stitches, it becomes necessary to employ a sheet of paper or other suitable material beneath the fabric operated upon to prevent the needle pulling the same or causing the stitches to catch up too much of the fabric and bunching; such condition stretching the fabric and distorting the same unless such paper or similarly placed material is used.

In the present invention, however, in the carrying out of which I employ two needles,

I effect a holding of the fabric, and intricate designs of an open character as well as solid embroidery can be produced without disturbing the plane surface of the same.

These objects and other details of my invention are more fully described hereinafter, reference being had to the accompanying drawings illustrating more or less diagrammatically the features of my invention, in which:

Figure 1, is a plan view of a figure of embroideryvmade in accordance with my process;

Fig. 2, is a perspective view of a series of stitches to form embroidery in accordance with the process forming the subject of my invention;

Fig. 3, is a plan view of a portion of such stitches;

Figs. 4, 5 and 6, illustrate other forms LOEB, a citi-" of stitches which may be produced in carrying outthe process'forming the subject of my invention, and

Fig. 7, is a view of the under side of the fabric showing the manner in which the loops of a plurality of sets of needle stitches upon the face of the fabric are held by a single shuttle thread.

In the process of producing the improved embroidery forming the subject of my invention, I employ a suitable form of sewing machine which may be of the same type as that described in my pending application filed December 12, 1911, Serial No. 665,395, or any other suitable machine, having a pair of needles disposed at fixed distances apart and mounted to oscillate; the movement of which oscillations regulates the length of the stitches. In the operation of the machine carrying such needles, provision may be made for regulating the extent of oscillation to determine the length of such stitches.

In operation, the pair of fixed needles are oscillated back and forth toward the operator, and the stitches as formed may be laid in their lateral disposition very close together or wide apart, as the character of design may suggest or require, and such disposal of the stitches is effected by the operator moving the fabric; the needles oscillating in a single plane. The fabric, carried by the usual tambour embroidering frame, may be moved laterally or otherwise with respect to the movement of the needles, although such movement may be accompanied by a movement almost in line with the movement of the oscillating needles. The resultant of these two movements, and the effect of any movement of such frame, is indicated by the character of the stitches formed, which are laid ordisposed in a position substantially diagonal with respect to the general direction of that portion of the design filled by the same. 7 L

In their formation, the sets of stitches formed by each needle may be laid in'two substantially paralleling rows; overlapping each other and being disposed in a position substantially diagonal with respect to each other and the general direction of that portion of the design covered by the same.

The stitches formed are laid so close together and overlap to such an extent that it is impossible to tell where one set of stitches begins and the other set leaves ofi. As in the process of embroidery set forth in my pending application, the stitches may be gradually lengthened or shortened independently to produce any desired effect, and by reason of the double row of stitches which overlap each other, there is a complete absence of loosely looped stitches.

The embroidery may be of the character illustrated in Figs. 2 and 3, in exaggerated form, in which the respective sets of stitches are in substantial parallelism and in which the narrowing of the embroidered portion formed by the stitches to follow the contour of the design is effected by moving the fabric with respect to the needles without shortening the stitches. In the formation of a thin line, therefore, the stitches lie diagonally with respect to such line, and in general their position is substantially diagonal with respect to the general outline or contour of the figures formed by the design.

In addition to this formation of the stitches, they may be formed short and long by giving the needles a short and long movement of oscillation, as shown in Fig. 4. In other instances the oscillations of the needles may be graduated during the formation of the stitches to produce automatically gradually lengthened stitches and gradually shortened stitches as may be desired in the covering of the design as shown in Fig. 5. Still other forms of embroidery may be effected and by giving the needles oscillations of extremely limited length it is possible to form paralleling rows of stitches as indicated in Fig. 6, which may blend into a single line.

In all instances, the loops of the two sets of stitches are caught by a single shuttle thread on the under side of the fabric.

In Figs. 1, 2 and 3, of the drawings, 1 represents the fabric; 2 one set of substantially paralleling stitches of one thread; 3 the other set of substantially paralleling stitches of the same thread; 2 one set of paralleling stitches of the first thread and 3 the other set of paralleling stitches of the second thread.

In Fig. i, illustrating a form employing short and, long stitches, the long stitches of one thread are indicated at 2"; and the short stitches of the same thread at 3"; while the long stitches of the other thread are shown at 2 and the short stitches of said thread at 3;

In Fig. 5, showing sets of gradually Copies of this patent may be obtained for five cents each, by addressing the lengthened and gradually shortened stitches, the respective threads are indicated at 5 and 6.

In Fig. 6, showing the paralleling rows of sets of stitches, the several sets of stitches are indicated at 2 3 2 3 respectively.

In Fig. 7, an exaggerated view of the stitch loops shown on the under side of the fabric is illustrated which may be taken as illustrative of all of the forms of stitches shown. In all instances, each set of stitches forms loops 4 and 4 on the under side of the fabric, and a single shuttle thread 7, engages such loops; the outside loops being, as noted, longer than the inner ones.

In some instances it may be desirable to make one stitch of' each set tight and the other loose, or one set of stitches formed by one of the needles may be tight and the other loose.

An important feature of the embroidery forming the subject of my invention is the ease and rapidity with which the design can be covered; the plurality of sets of stitches formed doubling the covering capacity of the same. i

I claim:

The process of embroidering, which consists in stretching a section of fabric in a tambour frame, oscillating, with respect to the fabric and in a fixed path, a pair of spaced needles carrying the usual threads, and manually moving the fabric in any desired direction independently of the means effecting the stitch formation whereby instantaneous changes in the position of the fabric with respect to the stitches laid by the oscillating needles may be effected, said needles forming a plurality of plural sets of stitches upon the face of the fabric, each plural set of stitches being formed of a separate thread and the stitches of the respective sets substantially paralleling each other; and each of said sets of stitches having a plurality of loops on the under side of the fabric connected. by a single thread wholly disposed on. the under side of the fabric.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
